Don't take an Absa Warranty.

I have a Absa vehicle warranty for 24months. In February, I was informed that the contract was ending in March & I shud renew. I agreed to this. However I was debited for the same vehicle in Feb for both the old & renewed contract. I disputed this since my contract was expiring latter March & it was paid for. The new contract amount shud b debited thereafter. However I am told that this is not the case. I reversed the Feb installment & have been debited for March & April but the warranty is on hold. Not sure if they understand that one cannot b expected to pay twice for 1 vehicle on renewal.
